Can Exercise Beat Depression? – Reader’s Digest Medical Update
Thursday, January 8th, 2009Aerobic exercise may be as effective as antidepressants if you work out enough, say scientists at the Cooper Institute in Golden, Colorado, and other medical centers. In a 12-week study of 80 people with midle to moderate depression, researchers found that working up a sweat on a treadmill or stationary bike reduced symptoms by 47%. That’s similar to the effect of antidepressants. But the amount of activity is key. Only those who worked out for three hours a week got the mood-bursting benefit. Thsoe who exercised just 80 minutes a week had no improvement. The researchers still don’t know exactly how exercisse helps, but they specualte that aerobic activity increases levels of serotonin and other brain chemicals that regulate mood. Talk to your doctor before you choose walking, biking or jogging ober therapy or drugs.
